Quality Control Based on Measurements from Verified Sensors

2. The method according to claim 1, wherein the one or more output values are instructed to be obtained via a given processor and the method further comprises verifying the given processor.

3. The method according to claim 2, wherein the method further comprises connecting to a computerized entity to verify each of the one or more sensors and the given processor, based on attributes of the given processor.

4. The method according to claim 3, wherein the method further comprises enrolling each of the one or more sensors and the processor at the computerized entity, prior to verifying the one or more sensors and the processor.

5. The method according to claim 3, wherein verifying the one or more sensors and the given processor comprises communicating identifiers of the one or more sensors and the given processor for the computerized entity to compare the communicated identifiers to reference identifiers.

6. The method according to claim 1, wherein the method further comprises enrolling each of the one or more sensors with a computerized entity by communicating one or more public keys and/or one or more certificates associated to the one or more sensors to the computerized entity.

7. The method according to claim 6, wherein verifying the one or more sensors comprises communicating signed versions of the two or more measurements values obtained from the one or more sensors to the computerized entity, where the signed versions have been obtained by signing the two or more measurements values using one or more private keys associated to the one or more sensors, for the computerized entity to verify the signed versions based on the one or more public keys or on one or more public keys derived from the one or more certificates.

8. The method according to claim 3, wherein the method further comprises verifying one or each of the given processor and the one or more of the sensors by interacting with the computerized entity to authenticate the one or each of the given processor and the one or more of the sensors, based on attributes of the sensors.

9. The method according to claim 3, wherein comparing the output values comprises querying the computerized entity based on the output values, for the computerized entity to compare the output values with the corresponding reference values and compute a value indicative of the quality assessment.

11. The method according to claim 10, wherein the external database is a computerized, distributed ledger.

12. The method according to claim 10, wherein the method further comprises connecting to a computerized entity for it to verify the one or more sensors and store the one or more verification values on the external database.

14. The method according to claim 1, wherein the two or more measurements values obtained comprise at least two measurements values relating to distinct properties as sensed by the one or more sensors.

16. The method according to claim 1, wherein a number of output values is larger than or equal to 1 and less than a number of measurements values.

17. The method according to claim 1, wherein the computerized process includes a feature extraction function, whereby the output values comprise a feature vector.

18. The method according to claim 1, wherein the computerized process comprises selecting a subset of the output values, whereby the subset of the output values are compared to the reference values, to obtain the quality assessment of the item or the technical process.
